HORIBA introduces LAQUAtwin compact water quality meter, incorporating 60 years of water quality analyzer research and manufacturing technology into a pen sized, simple design. Select from seven water quality parameters such as pH , conductivity, various ions (Na+, K+, NO3-, Ca2+) and salinity that suits your purpose. Bring LAQUAtwin with you wherever and whenever you want to. It is your “lab-in-the-field.”

Accurate reading from only a single drop, in a few seconds. Furthermore, select measurement method depending on your situation and sample. (Drops, Immersion, Scoop, Wipe,Solid samples, Powders, Paper, textiles and films)

pH, conductivity, ions and salinity. 7 parameters, 11 models.

Calibrate and measure at the touch of a button – the Smiley face will tell you when the result can be read.

Models & Details

Water pH varies in different environments, and a slight change can often have a major effect.

Whether you need to keep the pH of an aquarium within tight limits, are checking for the acidity of rain water or for the quality of meat and fish products, LAQUAtwin compact pH meters are ideal for you. No matter where and when you need to test.

Flat sensor technology and 60 years of sensor engineering realizes a reliable and direct measurement of a drop of the sample from 0.12mL. No need for a beaker to calibrate or measure. Just drop the standards and sample on the flat sensor, saves you time and minimize wasting your precious sample.Conductivity readings can be converted into salinity and TDS.

Only compact meter for a quick measurement of sodium ion using ion selective membrane.Flat sensor technology and 60 years of sensor engineering realizes a reliable and direct measurement of a drop of the sample from 0.3mL. No need for a beaker to calibrate or measure. Just drop the standards and sample on the flat sensor, saves you time and minimize wasting your precious sample.

Applications include:

Plant sap testing

Health management;

food quality control;

environmental measurement;

salt water damage testing.

Note: Ion measurement can be affected by non-target ions (see brochure for details). Detection of ion in water only; electrolytes in oils cannot be measured.

The only pocket meter that directly measures conductivity in 0.12ml sample and converts it into salinity or salt concentration. No need for a beaker to calibrate the meter or measure a sample. Just place few drops of the standard or sample onto the sensor. This procedure saves you time and prevents wasting your precious sample.
